PROBLEM: Postoperative nausea and vomiting remains an important problem. Many risk factors have been identified; however, the importance of postoperative analgesic technique and patient expectation remain poorly defined. METHODS: We prospectively collected data on postoperative nausea and vomiting (PONV) in four groups of randomly selected patients (n=50 per group) who received either simple analgesics, nurse-administered intravenous morphine (NAA), patient-controlled analgesia (PCA) with morphine or epidural analgesia with bupivacaine and fentanyl. Patients were questioned regarding any past history of PONV or motion sickness, their preoperative expectation of suffering PONV and satisfaction with their antiemetic therapy. RESULTS: The incidence of nausea was higher in both morphine groups P<0.05), women (P<0.05), those less than the median age of their group (P<0.05) and those with a past history of PONV (P<0.05) or motion sickness (P<0.05). Most patients did not expect to experience PONV (19.3%). The incidence of nausea was higher in those expecting to experience PONV than in those not expecting to suffer PONV (P<0.01). Of those who received postoperative antiemetic treatment, 23.6% were dissatisfied or very dissatisfied with their therapy. Few patients received a prophylactic antiemetic drug (15%). CONCLUSIONS: Study results show that patient expectation is a potent predictor of postoperative nausea, a risk factor hitherto ignored in the anaesthetic literature, and that, in the provision of analgesia following major surgery, epidural analgesia is associated with less PONV than intravenous morphine. 相似文献

Previous studies on post-operative pain, nausea and vomiting tend to be quantitative in method and focus on in-patient or day case surgery. The objectives of this study carried out in one specialist eye hospital in England were to consider post-operative pain, nausea and vomiting from a qualitative perspective. Fifty-five patients undergoing general anaesthetic short-stay ophthalmic surgery (orbital hydroxyapatite implantation) consented to participate in telephone interviews 8 days post-surgery. The interviews lasted between 20 and 60 minutes. Data were analysed thematically and offer insight into varying experiences of pain, nausea and vomiting in hospital, on discharge and at home. Results indicate that not all patients were discharged home in optimum condition. The needs of post-operative short-stay patients should come before financial imperatives to vacate beds. Patient education and information giving is discussed in the light of the findings. 相似文献

Appetite loss, nausea and vomiting are most common gastrointestinal distress in patients with advanced cancers. It is worthwhile to relieve these symptoms for improving their quality of life (QOL), an inadequate treatment, on the contrary, will increase their distressing symptoms. To avoid this, it is essential to clarify the cause of illness, especially to find out whether it is due to a complete mechanical gastrointestinal obstruction or not. If it is so, the use of metoclopramide is a contraindication. Practically, the combined use of octreotide acetate, steroids and morphine will be effective to manage a severe gastrointestinal distress such as an obstinately nausea and vomiting. 相似文献

Nausea and vomiting in abdominal cancer is perhaps one of the most difficult symptom complexes to manage, especially when complicated by bowel obstruction. There are many mechanisms of nausea in advanced abdominal cancer with a number of therapeutic interventions that can significantly enhance symptom control and overall quality of life. As with pain, the ideal approach should include a mechanistic analysis of the causes of nausea beginning with a thorough history, followed by a directed physical examination, and selected laboratory studies. The symptom history, in conjunction with a physical examination and directed tests should direct appropriate pharmacologic and nonpharmacologic interventions. The result is often the amelioration of significant suffering and enhanced quality of living. 相似文献

A commonly reported consequence of post-treatment nausea or vomiting is the development of anticipatory nausea and vomiting
(ANV). In most published work, nausea is reported to occur before chemotherapy drugs are administered by approximately 20%
of patients at any one chemotherapy cycle and by 25–30% of patients by their fourth chemotherapy cycle. Most studies in adult
patients strongly support the view that the development of ANV involves elements of classical conditioning. The best method
to avoid development of ANV is to adequately prevent both vomiting and nausea from the first exposure to chemotherapy. If
anticipatory side effects develop, behavioral treatment techniques, such as systematic desensitization, have been shown effective.
Benzodiazepines used in combination with behavioral techniques or antiemetics may also be useful. The evidence on which these
conclusions are based is reviewed in this article. 相似文献

Nausea and vomiting (N&V) is among the most distressing side effects of chemotherapy, despite the development of more efficacious antiemetic agents. As many as 60% of patients who receive cancer chemotherapy experience some degree of N&V. However, the actual incidence is difficult to determine with accuracy because of the variety of drugs, doses, and health conditions of the patients who receive cancer treatments. This article examines the state of the science related to chemotherapy-induced nausea and vomiting and reviews both pharmacologic and behavioral strategies that have demonstrated efficacy in managing these distressing symptoms. 相似文献

Anticipatory nausea and vomiting 总被引:1,自引:0,他引:1
Anticipatory nausea and vomiting (ANV) is not only a learned response but can occur without prior exposure to chemotherapy depending on patient emotional distress and expectations. The best method to avoid development or reinforcement of ANV is to avoid both vomiting and nausea from the first exposure to chemotherapy. If ANV develops, benzodiazepines have been documented to help in adult patients, and several psychological techniques are also of help, including systematic desensitization. The evidence on which these conclusions are based is reviewed in this article. 相似文献

A comprehensive history and physical examination can often reveal the cause of nausea and vomiting, making further evaluation unnecessary. Acute symptoms generally are the result of infectious, inflammatory, or iatrogenic causes. Most infections are self-limiting and require minimal intervention; iatrogenic causes can be resolved by removing the offending agent. Chronic symptoms are usually a pathologic response to any of a variety of conditions. Gastrointestinal etiologies include obstruction, functional disorders, and organic diseases. Central nervous system etiologies are primarily related to conditions that increase intracranial pressure, and typically cause other neurologic signs. Pregnancy is the most common endocrinologic cause of nausea and must be considered in any woman of childbearing age. Numerous metabolic abnormalities and psychiatric diagnoses also may cause nausea and vomiting. Evaluation should first focus on detecting any emergencies or complications that require hospitalization. Attention should then turn to identifying the underlying cause and providing specific therapies. When the cause cannot be determined, empiric therapy with an antiemetic is appropriate. Initial diagnostic testing should generally be limited to basic laboratory tests and plain radiography. Further testing, such as upper endoscopy or computed tomography of the abdomen, should be determined by clinical suspicion based on a complete history and physical examination. 相似文献

Despite great strides during the preceding 3 decades, the ability to consistently eliminate postoperative nausea and vomiting (PONV) continues to elude anesthesia practitioners. The occurrence of PONV related to anesthesia and surgery prolongs hospital stays and increases healthcare costs. Protracted recovery times place constraints on patients, healthcare systems, and healthcare financiers. Many pharmacological antiemetics have been developed and are in use in the attempt to alleviate PONV. Side effects and cost profiles of many of these interventions, however, reinforce the broadly held belief that there remains opportunity for improvement. Because the Western culture almost exclusively favors evidence-based scientific practice and interventions, the search continues for an ideal, cost-effective, safe, and efficacious pharmacological agent to prevent PONV. Eastern culture, on the other hand, relies heavily on naturopathic remedies whose successful use has spanned thousands of years. Increasing attention has been given to the potential benefits of nonpharmacological intervention for the prevention of PONV in association with anesthesia care. Therefore, the purpose of this AANA Journal course will be to focus attention on what is known and what is unknown in the literature regarding use of the nonallopathic remedy of acupressure as a nonpharmacological alternative to commonly utilized antiemetic prophylaxis. 相似文献
